Counterdiabatic quasi-Floquet control for the generation of entangled BICs using giant atoms
Alexis R. Legón, Pedro Orellana, Ariel Norambuena
Bound states in the continuum (BICs) provide a mechanism for preserving entanglement in waveguide quantum electrodynamics. Here, using quantum control techniques in a configuration…
Quantum Magic Reveals CP Phases Invisible to Entanglement in Spin-0 Decays
Nicolas Viaux, Ariel Norambuena, Pedro Orellana
All standard scalar quantum-information measures -- concurrence, negativity, entanglement entropy, the optimized CHSH bound, and quantum Fisher information -- are CP-blind in ideal…
Geometric control of maximal entanglement via bound states in the continuum
Alexis R. Legón, Mario Miranda Rojas, Pedro Orellana +1
Bound states in the continuum (BiCs) convert dissipative open systems into effectively closed quantum subspaces through destructive interference. We show that two identical giant a…
Topological bound states in the continuum
Dunkan Martinez, Rodrigo P A Lima, Alexander Lopez +2
Bound states in the continuum, originally proposed within the framework of quantum mechanics, have since been observed in a variety of physical contexts, including electromagnetism…
Unconventional Floquet topological phases in the SSH lattice
Dunkan Martínez, Yuriko Baba, Benjamín Santos +4
Topological materials, known for their edge states robust against local perturbations, hold promise for next-generation quantum technologies, but remain scarce in nature and challe…
